When Twilight, Rainbow, and Fluttershy got to the top, it was different then what they thought.
The front was rigid with different icy structures while the back was a flat ice plain. They landed at the edge of the plain.
Twilight put a hoof on it and it was thin ice. She stepped on it and it cracked under her weight.
"Is the glacier...melting?" Fluttershy asked. "I believe so" Twilight said. "It can't be that bad, right?" Rainbow asked.
"I don't know. Why don't we find out" Rainbow then had an idea. She flew up high into the sky and sky dived. She smashed into the thin ice.
It cracked under her weight and the force of her landing caused the entire ice plain to crack as well. "Well, now we know" Rainbow said.
Then, the ice gave way and Rainbow fell into the water underneath. "Rainbow Dash!" Twilight and Fluttershy shouted.
They ran over and helped Rainbow out of the water. Rainbow was shivering from the cold water. "Are you okay?" Fluttershy asked.
"Yeah. I'm fine" she said with a little bit of shivering in her voice. "That water's cold" she said. "Well, it is frozen over after all" Fluttershy replied.
Twilight then looked where the ice plain was and noticed something that shocked her extremely.
"Guys, you should come look at this" Tweilight said and Fluttershy and Rainbow flew over and they were shocked.
The ice had drifted apart from Rainbow's impact to reveal the true threat. The icy plain had now become an huge body of water.
"It's all gonna flood" Twilight said. "We better let everypony know right away" Twilight said getting ready to leave.
"Maybe we could turn everypony into sea ponies" Rainbow suggested. "I don't think Queen Novo would agree to that, Rainbow Dash." Fluttershy said.
"Hey, it's just a suggestion." Fluttershy rolled her eyes and the 3 headed back to warn everypony of the coming flood.
Meanwhile, everypony was nervous for what the 3 would bring back about the glacier, especially the Mane 6.
"What do you think is going on" Applejack asked the others.
"From the looks of it, it looks like the glacier's melting because when ice melts, doesn't it turn into water?" Pinkie said.
"Pinkie's right" Starlight said, "The glacier is most definitely melting." "But, does that mean Equestria will...flood!?" Spike said.
The others gasped and Rarity nearly fainted. Then, Twilight, Rainbow, and Fluttershy returned. "What's the news?" the Mayor asked Twilight.
"I'm afraid a flood will happen" Twilight said. Everypony gasped. "From the looks of it, we may have only a few days before the flood comes" Twilight continued.
Now, everypony started panicking. "But don't worry, I'll talk to the princesses and see what they and I can do. For now, we should start evacuating"
Everypony grew a little sad. "Grab all your most important possessions and we'll head out when everypony's ready."
Everypony nodded and they headed out to grab their things and start the evacuation. Twilight landed with Fluttershy and Rainbow landing next to her.
The rest of Mane 7 came to Twilight. Twilight shed a tear for there was no way to save Equestria itself this time.
Rainbow put a hoof on Twilight's shoulder and they all engaged in a big group hug. Twilight then grew confident and she knew she could at least save everypony.
"Alright, you guys need to get ready for the evacuation. Help everypony with it, okay. I'm going to tell the princesses the situation" Twilight said.
They all nodded and went to help lead the evacuation. Twilight then took off towards Canterlot.
